In a typical nuclear fission reaction, a heavy nucleus decays into daughter nuclei which are lighter and have higher binding energy per nucleon. For example:
U-235 + n --> U-236 --> Ba-141 + Kr-92
In the Atomic-mass vs. Binding-Energy-per-Nucleon graph, both
Kr are further up the curve towards
Do fission reactions exist where one of the nuclei is "over the hump"?
For example, could one daughter nucleus of fission be
F-19? If not, why not?
If yes, could one daughter nucleus have lower binding energy per nucleon than the original atom (even if the total binding energy per nucleon increases overall?)
